Can I have some help with this pls

$21,000

Step-by-step explanation:

(refer to attached for reference)

Assuming simple interest, the applicable formula is

A = P(1 + rt)

Where:

A = final amount (we are asked to find this)

P = Principal (Beginning amount) = $15,000

r = annual interest rate = 12% = 0.12  (i'm assuming that we are given annual rate)

t = time = 40 months = 3.333 years

Hence substituting all the above into the equation,

A = P(1 + rt)

A = (15,000) [1 + (0.12)(3.333)]

A = $21,000

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
